The Summer House....

...at least that's how the Sparrows (more than 2) seemed to be treating this empty nest box in the garden, they were very busy going in and out of it, looking around it, and generally it seemed - squawking loudly (see the one extra), giving the kids next door a run for their money ;-)

This box has been there for a good couple of years, so I'm very intrigued. One thing for sure, mother nature is full of surprises :-)
